HolyTerra opened a new issue #17733: "Segmentation fault: 11" after "Running: OpWrapperGenerator.py"
URL: https://github.com/apache/incubator-mxnet/issues/17733
## Description
I tried to build MXNet from source,but failed each time after Running: OpWrapperGenerator.py.
### Error Message
[ 93%] Built target mxnet
Running: OpWrapperGenerator.py
Segmentation fault: 11
make[2]: *** [cpp-package/CMakeFiles/cpp_package_op_h.dir/build.make:59: cpp-package/CMakeFiles/cpp_package_op_h] Error 255
make[1]: *** [CMakeFiles/Makefile2:2229: cpp-package/CMakeFiles/cpp_package_op_h.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....
[ 93%] Built target image-classification-predict

make: *** [Makefile:141: all] Error 2
## Environment
Ubuntu 19.10, CUDA 10.2, OpenCV 4.2
gcc/g++ version is 7.4.0,build with c++14.
I chose USE_CPP_PACKAGE, set BLAS to MKL and CPU runtime to TBB.
## What have you tried to solve it?
1.I switched BLAS from openblas to MKL because of issue #11543, but it doesn't work.

After switching to MKL, you may run into https://github.com/apache/incubator-mxnet/issues/17641
Can you try deleting `3rdparty/openmp` to see if the segfault is due to conflict between llvm openmp and intel openmp?
